Production-location decision and free entry oligopoly: A correction

This paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].

当前中国农民合作社开展信用合作的典型模式、问题与建议

农民合作社开展信用合作是我国新型农村合作金融发展研究的重点。本文结合调研情况，对以赊销为特征的商业信用合作、以资金互助或担保互助为核心的货币信用合作、依托产业链或银政资金的混合式信用合作三种不同模式进行梳理分析，并从政策制度、现实操作、潜在风险点三个层面指出了当前中国农民合作社开展信用合作的主要问题。推动农民合作社信用合作持续健康发展，必须坚持服务“三农”的政策导向、强化对信用合作不同发展模式的分类指导、妥善处理风险防控和内在活力的关系、进一步规范信用合作管理、切实防控信用合作风险、充分发挥信用合作综合带动作用。     

会计计量与企业债券信用评级关系的应用分析——基于2006年新会计准则的思考

企业债券信用评级是企业发行债券的重要步骤,债券评级对会计信息具有依赖性,而会计信息的计量属性会直接影响会计信息,不合适的会计计量属性会对债券评级造成负面影响。本文结合2006年的新会计准则的相关规定和企业债券信用评级的特点,通过分析会计计量对信用评级的误导因素,认为借鉴国际先进经验,可以提高债券评级的可靠性和客观性,促进企业融资市场的公平性和公正性。     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.

Testing vertical price transmission for Vietnam's Robusta coffee

Vietnam has undergone market reforms over the last three decades; and as a consequence, the coffee sector has become increasingly market‐driven. The success of the government's liberalisation policies in terms of market efficiency is investigated by examining the transmission of both positive and negative price changes for Robusta coffee between export and farmgate prices. We used a threshold vector error correction model and high‐frequency daily data. The primary result here is that of a symmetric price transmission between export and farm‐level prices. This result holds when tested with weekly price data, derived from the daily data. Farmgate prices respond faster to decreases than increases in export prices when the long‐run deviation exceeds a certain threshold. These price changes are transmitted within several days. This research also confirms the importance of transaction costs, and other price frictions mostly ignored in prior analyses for coffee.
